Why is it called lost wax casting?

After closing the mold around the clay model, hot wax is poured into the gap between the model and the mold. This causes the wax to melt and flow out of the mold, leaving a space between the fire resistant clay model and the investment mold. This is why this method is called the lost wax process.

What is the lost wax technique in dentistry?

The technique employed is known as the “lost-wax casting process”. The name means that in this process, the wax, which is the model of the cast item, is totally burned away without leaving any residue, and then molten metal alloy (for instance gold alloy) fills this space during the casting process [11].

Advantages of Lost-Wax Moulding:

• The process is especially advantages for high-melting-point alloys as well as for difficult-to-machine metals.
• It is most suitable for producing small castings having intricate shapes.
• It maintains a very close tolerance of about ± 0.05 mm.
• It produces very smooth surfaces.
